Переведите текст на русский язык:
The Indian and Two Travellers
Two men were travelling in a very wild part of America. They saw no modern houses and no traces of civilization for many days. What they saw were only a few huts (хижины) made of wood or tents where Indians lived. One day they met an old Indian who did not work but hunted animals and ate them as his food. He was very clever and knew everything about the forest and the animals living in it and many other things. He could also speak English quite well.
"Can you tell us what the weather will be like during the next few days?" one of the two travellers asked him. "Oh, yes," he said. "Rain is coming, and wind. Then there will be snow for a day or two but then the sunshine will come again and the weather will be fine." "These old Indians seem to know more about Nature than we with all our science," said the man to his friend. Then he turned to the old Indian.
"Tell me," he said, "how do you know all that?" The Indian answered: "I heard it on the radio."
